A practice approach for identifying previously unsuspected environmental contributors to systemic lupus erythematosus and other complex diseases.

Abstract

Existing medical records and health surveys provide insights into potential environmental contributors to complex chronic diseases. Those recognizable risks (e.g., workplace exposures and behaviors including smoking) do not, however, exhaust the domain of potential environmental contributors. Qualitative ethnographic investigation can be used to generate statistically testable hypotheses about environmental contributors to complex disease that otherwise would not be recognized as such. Consequently, we can empirically specify lifestyle beliefs and behaviors usually summarized by proxy identities such as race, ethnicity, gender, class, and culture. The investigation of potential environmental contributors to complex diseases may be particularly useful in confirming or disconfirming suggestive or established linkages and for indicating the kind of gene-environment interaction that may be involved.

Natural radioactivity intake into wheat grown on fertilized farms in two districts of Pakistan.

The use of phosphate fertilizers on agricultural farms enhances gamma-ray activity concentration in the farms and therefore absorbed dose rates to the public. The most common natural radionuclides in fertilizer and soil are (40)K, (226)Ra and (232)Th. Agricultural farms at four locations in two districts in Pakistan consisting of saline and normal soils had been under fertilizer treatment for the past 30, 20, 10 and 0 y, therefore, natural radioactivity has been measured in soil samples from these sites to investigate the effect of fertilizers in soil and wheat grown in these sites. Radioactivity measured in soil of the sites under investigation was 550-644, 20-35 and 42-58 Bq kg(-1) for (40)K, (226)Ra and (232)Th, respectively. Wheat was grown in the farms and radioactivity transferred from soil to roots, shoots and grains was also measured. Relatively high natural radioactivity has been observed in the fertilized agricultural farms and in the wheat plants grown in these farms. From the total amount of an element uptaken in a plant, distribution of the element in different parts of the plant has been studied. The distribution of potassium was almost uniform in roots, shoots and grains of wheat; that of radium was different in the three parts of wheat; and that of thorium was almost equal in shoots and grains but quite large in the roots. Soils to grain transfer factors of the natural radionuclides have been determined as 3-4 x 10(-2) for (226)Ra, 2-3 x 10(-2) for (232)Th and 17-20 x 10(-2) for (40)K. Annual doses of (40)K and (226)Ra received by intake of grain products have been estimated to lie within range while the dose received from intake of (232)Th is larger than the range specified in UNSCEAR report 2000.
